INCORPORAÇÃO DO RESÍDUO SÓLIDO DO TRATAMENTO DE EFLUENTES DO SETOR DE ESMALTAÇÃO DE UMA CERÂMICA VIA SECA EM ENGOBES

Abstract

Given the problems of reusing industrial waste generated in the glazing line of a dry ceramic plant, an application was studied that would increase the added value of the solid waste from the effluent treatment of this sector. Thus, the characterization with X-ray Fluorescence (XRF) and dilatometry analyses of this waste was carried out for three months of the year, in order to create a small history and evaluate its constancy. From this, applications were carried out on ceramic biscuits in a test line using the veil-bell method with percentages of 2%, 5% and 10% of the diluted solid waste and the ceramic plates were fired in an industrial kiln. To validate the study, tests of hue, warpage, contamination under a digital microscope and cracking of the fired plates were carried out. The results show that it is possible to use the sludge cake, with the residue from April showing the best results.
